2014-04-17: Moved the version control to GIT. To check out see the tab "Code". Note that the whole history including ancient CVS, then some time in monotone, then subversion was united into one GIT repository thanks to ESR's reposurgeon.
2013-05-29: Maintainers of github fork "pyst2" contacted to join forces. Note that the last release here fixes the same bug as on github, otherwise github version seems to only contain cosmetic changes and examples.
2012-07-06: An offer to maintain the project has been received.
2012-01-29: There have been two or three forks that are being maintained.
This is now just history unless someone cares to take up maintenance here.
